A quality photocatalytic activity of an amorphous titanium oxide film achieved using the selectively photochemical etching and its application for the organic light emitting diode encapsulation

Characterization of an Amorphous Titanium Oxide Film Deposited onto a Nano-Textured Fluorination Surface

“…In our previous report, we developed a selectively fluorinated etching on the a-TiO x film to result in a nano-textured surface with the incorporation of fluorine ions [ 13 ]. Such film exhibited a high photocatalytic activity that was comparable to that of the TiO x film with an anatase structure and was applied to package the blue-light organic light emitting diode to result in a device with a self-cleaning function [ 14 ]. The apparent improvement on the film’s photocatalytic activity was a mechanism of the formation of the Ti–F functional group for facilitating the separation of the photo-produced charge couples and the increase in the reactants’ adsorption as a consequence of the large specific surface area.…”
